Improvement in automatic boiler-feeders



G. lV. B. GEDNEY AND XV. J. BRASSINGTON, OF NEV YORK, N. Y.

IMPROVEMENT IN AUTOMATIC BOlLPt-FEEDERS.

Specification forming part of Letters Patent No. 3.579, dated July 19, 1864.

To all whom t may concern.-

Be it known that we, G. W. B. GEDNEY and W. J. BRAssrNeToN, of the city of New York, in the county of New York and State of New York, have invented a new and useful Machine for Supplying Steam-Boilers with Water 5 and we do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Fig'ure l is a perspective view, and Fig. 2 is a vertical section.

A is an air-tight vessel, connected with a boiler, N, by pipes B and B2 at the top, and by pipe U at the bottom.

l) is a pipe to admit cold water (or the water for the boiler) into vessel A at top of said vessel, the water to be drawn from a tank or cistern by vacuum formed in vessel A. rlhe operation can be understood by referring to section, Fig. 2, representing the internal arrange ment.

E is a iloat, moving easily up and down upon rod F in center of vessel A. This rod' 1s attached at the upper end to arms G and H by a joint. Arm G opens and closes a steam-cock or small slide-.valve or any other device for letting in and cutting oli' steam from pipe B at M. Steam-pipe B2 has a stop-cock at l, to be opened and shut by hand to start the operation of the machine. Pipe D has a lifting valve at K, and pipe C, connecting vessel A with the boiler at the bottom, has a lifting valve at L. Now, it is obvious that itA the cock I is opened and steam is admitted into vessel A until all air is expelled, and then closed, condensation will immediately take place in Vessel A and cold water iiow up and through pipe D until vessel A is lled. As tie water flows into vessel A, the oat E bejgins to rise with the water until it reaches a small button upon rod F at O, when the iloat moves the arms G and H, attached to stopcock or valve M, and opens the same, whereby steam is admitted into vessel A, and the water instantly ceases to run up and through pipe D. As the pressure of steam becomes the same in vessel A that it is in the boiler N, said vessel A being raised above the waterlevel of the bciler, as seen at R, the Water from its natural gravity will run from vessel A through pipe C and valve L into the foot of the boiler at S. At the same time the float E arrives at the bottom, bringing down rod F and arms G and H by coming in contact with the button P on the bottom of rod, thereby cutting oft1 steam at M when condensation immediately begins again, and the action of the apparatus continues as long as any steam remains in the boiler or until the water rises in the boiler high enough to cover the oritice of pipe B at R. Upon the arm Il is placed a spiral spring to accelerate the motion of arm G (after it has passed a level) in opening and closing the cock or valve M.

T is a glass tube placed on the side of vessel A, having communication at both top and bottom with inside ot vessel to show the use and fall ot' Water therein.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. lhe arrangement consisting' ot` the vessel A, float E, rod F, arms G H, pipes B (l D, and cock or valve M, applied on the outside oi' the boiler, and the whole constructed and operating substantially as and for the purposes setfoith.

2. The arrangement of the devices B2 I with a boiler and the feed-water apparatus specified, substantially in the manner and for the purpose descrlbed.
